63543883 ÷ 780 
Let's see how many times 780 fits into 63543883.

Going ahead to step 1:
The number 780 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 780

Let's proceed to step 2:
When dividing 63 by 780, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Bring next digit (5) of the dividend behind the 63 and repeat the process: 635 / 780

Advancing to step 3:
780 goes into 635 0 times with a remainder of 635.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 635, we get 635.
Bring next digit (4) of the dividend behind the 635 and repeat the process: 6354 / 780

On to step 4:
780 goes into 6354 8 times with a remainder of 114.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 6240 from 6354 and we're left with 114.
Bring next digit (3) of the dividend behind the 114 and repeat the process: 1143 / 780

Let's proceed to step 5:
If we divide 1143 by 780, we get 1 and a remainder of 363.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
The remainder is 363 after subtracting 780 from 1143.
Append the next digit (8) from the dividend to 363 and continue with: 3638 / 780

Moving on to step 6:
The number 780 fits into 3638 4 times, leaving a remainder of 518.
The number 4 becomes the next digit in our result. 
Result so far: 814.0
If we subtract 3120 from 3638, we get 518.
Append the next digit (8) from the dividend to 518 and continue with: 5188 / 780

Let's proceed to step 7:
If we divide 5188 by 780, we get 6 and a remainder of 508.
The number 6 becomes the next digit in our result. 
Result so far: 8146.0
Deduct 4680 from 5188 and we're left with 508.
Grab the next digit (3) from the dividend, add it to 508, then carry on: 5083 / 780

Let's proceed to step 8:
The number 780 fits into 5083 6 times, leaving a remainder of 403.
Record the quotient 6 as the next digit in the result. 
Result so far: 81466.0
Deduct 4680 from 5083 and we're left with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Moving on to step 9:
When dividing 4030 by 780, we get 5 with a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 81466.5
Subtract 3900 from 4030 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
When dividing 1300 by 780, we get 1 with a remainder of 520.
Write down 1 as next digit of the result. 
Result so far: 81466.51
If we take 780 away from 1300, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 11:
The number 780 fits into 5200 6 times, leaving a remainder of 520.
The next digit of our result is 6. 
Result so far: 81466.516
Subtract 4680 from 5200 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 12:
5200 divided by 780 is 6 with a remainder of 520.
Write down 6 as next digit of the result. 
Result so far: 81466.5166
The remainder is 520 after subtracting 4680 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

After the division, we end up with 81466.5166 and a remainder of 0.0052.
